Very interesting discussion! I am having a question regarding this. I work the same way as member s3w47m88. I copy the main theme, and then amend it. I amend most files, content, content-single, content-page, functions, header, footer, I pull in additional headers etc. So I am building my own theme based on the current WP theme.
What I don’t quite understand is this – if I replicate this as a child theme, amend most of the files, what will an update bring to my child theme if most parts are amended?
Many thanks.
